BARRIERS TO ENTRY

Institutional, government, technological, or economic restrictions on the entry of participants into a market or industry. The four primary barriers to entry are: (1) resource ownership, (2) patents and copyrights, (3) government restrictions, and (2) start-up cost. Barriers to entry are a key reason for market control and the inefficiency that results. In particular, monopoly, oligopoly, monopsony, and oligopsony often owe their market control to assorted barriers to entry.
